Answer / sandeep

D/y

Answer / prashant

Distribution transformers are always D/Y. This is coz while
we are transmitting power from the generation station we
only transmit as R,Y,B. Say in the case of large industries
11 KV supply is given directly which is stepped down using
D/Y transformer. the neutal we take from the Y end

Answer / gopi

the answer is delta/star. bcoz in distribution system we
use always step down tranformer and in the system netural
point is more important for industrieal loads. suppose we
connect transformer in star/delta connection, no neutral
point is comming.
